My audio setup on OBS looks like this:

My default audio and communications device on my computer are the Astro w/ the mixamp. I do have a 1200 millisecond delay on both the webcam and audio, however, it does not delay the audio at all.

Post a logfile. And a VOD if possible, demonstrating the issue.

The most common cause of audio looping/doubling is having your livestream open and un-muted in a browser tab.
The second-most common is leaving an audio device enabled for your webcam (picking up your voice from both your headset mic AND the webcam mic, leading to the doubled audio); should disable the webcam audio entirely if you'll be using a headset mic.

Here is an example from my stream:

Here is my current audio setup in OBS, and I DO have the microphone disabled from my webcam.

You're using the mixamp for both your desktop and mic audio. Uncheck 'use input device for desktop audio', and select the appropriate speaker-set.

That option is mostly meant for those who are running their desktop audio out, through a mixing/VST stack, then back into the PC via a line-in, or those using a two-system casting rig without audio-over-HDMI, but want to keep their mic levels separate. As-is, you're double-pumping the same signal through both channels, causing the 'echo'.
